Bicycling Facilities
ASL = Advanced Stop Line (typically, before a BWB; sometimes only to allow room for long vehicles to turn left from the cross street)
BL = Bike Lane
BWB = Bicycle Waiting Box or bike box (between an ASL and the bicyclists’ stop line, or the crosswalk)
CT = Cycle Track
DZBL = Door Zone Bike Lane
FBL = Faux Bike Lane (typically a shoulder that is narrower than a std bike lane, often marked with bike route signs)
RD = Road
SP = Sidepath
SUP = Shared Use Path (formerly called MUP = Multi-Use Path)
Bicyclist Specific Laws
3FP = Three Foot Passing
BIT = Bicycles Impede Traffic (Impeding traffic law does not exclude bicyclists, as we find in 6 US states: CA, MI, NH, OH, PA, TX)
FTR = Far To Right (discriminatory law that requires only cyclists, and not other drivers, to ride near road edge when in a marked lane. This bad law takes away cyclists’ lane use rights)
LRA = Local Regulation (of bicycling movements) Allowed (this means that any city or county can enact its own custom, and often highly restrictive cycling laws, or ban cycling altogether.)
MBL = Mandatory Bike Lane (discriminatory law that requires cyclists to use a preferential use lane, whereas other drivers are NOT required to use HOV or Bus preferential use lanes)
MH = Mandatory Helmet
MSP = Mandatory Side-Path (discriminatory law that requires cyclists to use paths that parallel a road. This bad law takes away cyclists roadway rights and in many cases highway rights.)
MSU = Mandatory Shoulder use (discriminatory law that requires cyclists to use shoulders instead of the roadway. This bad law takes away cyclists’ roadway use rights.)
TAR = Two Abreast Riding
Concepts/Notions
BLOS = Bicycle Level Of Service (Often defined in a way that scores perceived “comfort” above traditional LOS metrics like flow/delay)
LOS = Level Of Service (The measure of effectiveness of a road to drivers, usually a measure of free-flowingness, with a free flowing road having a high LOS and a road with delay or congestion having a low LOS, graded from A to F, like school letter grades)
ROS = Right of Speed (The belief that having higher speed than another drivers gives the faster driver the “right” not to be delayed by the slower driver)
Roadway/Highway Facilities
2LR = 2-Lane Road = one lane in each direction of travel
3LR = 3-Lane Road = one lane in each direction + CTL
4LR = 4-lane Road = two lanes in each direction of travel
BMUFL = Bikes May Use Full Lane
CC = Coffin Corner (or SS for Suicide Slot)
CLRS = Center Line Rumble Strip
CTL = Center Turn lane (AKA 2WLTL)
LTOL = Left Turn Only Lane (or LTL for Left Turn Lane)
Multi-lane road = 2 or more lanes in each direction of travel
NLR = N-Lane Road = N/2 lanes in each direction (where N = 4, 6, 8, etc…)
RPM = Raised Pavement Marker
RS = Rumble Strip
RTE = Request To Experiment
RTOL = Right Turn Only Lane (or RTL for Right Turn Lane)
SLM = Shared Lane Marker (AKA Sharrow)
SS = Stop Sign
SW = Sidewalk
TCD = Traffic Control Device
TCDs = Traffic Control Devices (signals, signs, barriers/islands and markings)
TL = Traffic Light
TWLTL or 2WLTL = Two Way Left Turn Lane (AKA Center Turn Lane)
WCL = Wide Curb Lane (similar to Wide Outside Lane)
WOL = Wide Outside Lane
Maneuvers
LT = Left Turn
Ninja = Cycling at night without lights, sometimes even without reflectors
ROW = Right Of Way
RT = Right Turn
SWSS = Single Witness Suicide Swerve
Salmon = Wrong-way cycling
UT = U-Turn
